Top Fuel Dragsters

Among the faster-accelerating machines in the world, 10,000 horsepower Top Fuel dragsters are often referred to as the “kings of the sport," and with good reason. They are capable of covering the dragstrip in less than 3.7 seconds at more than 330 mph. Powered by a supercharged and fuel injected 500-cubic-inch adaption of the gamed Chrysler Hemi engine, Top Fuel dragsters can burn up to 15 gallons of nitromethane fuel during a single run. Constructed of chromoly steel tubing and carbon-fiber compositem Top Fuel cars are 25 feet long and weigh 2,330 pounds in a race-ready trim. 

Top Alcohol Dragsters

Top Alcohol dragsters may look like Top Fuelers, but they have significant differences. Whereas Top Fuelers use supercharged, nitro-burning engines, Top Alcohol dragsters may use a supercharged methanol-burning engine or an injected nitromethane combination. The injected nitro cars do not use a transmission, and the supercharged cars have three forward speeds. Weights vary according to combination but are generally between 1,975 and 2,125 pounds. Like Top Fuelers, Top Alcohol dragsters are restricted to a maximum wheelbase of 300 inches. Performances can be in the 5.1s at more than 285 mph.
